The processing of wood from stem to an end product is always associated with the appearance of low rate timber and saw mill waste. In contrast to softwood, however, cascade utilization of hardwood has not yet been established. The energetic use dominates, although the production of wood based materials and use as a substance or chemical product is possible. The current amount of hardwood in particle materials and fibre materials (10 % bis 40 %) could rise to 100 % (e.g. Klauditz, 1952; Kehr und Schilling, 1965a, b; Grigoriou, 1981; Vos und Kharazipour, 2008; Krug und Mäbert, 2007). As a substance, hardwood can be used in the food industry, to filter certain heavy metals or to produce plastics, linoleum or biomateials. By applying wood chemistry, cellulose facilitates the extraction of pulp, paper, cellulose ester, cellulose ether, wood sugar and regenerated cellulose. Lignin can be used multifariously as a raw material for example vanillin, binders, fertilizers or bio-materials.
